Reliable, tough and easy to ese—Hydro-rain's HRA valve has it all. Anti-siphon valves that prevent drinking water from being contaminated by irrigation backflow must be dependable. They must also be rugged enough to provide continuing protection even in punishing environments. In areas where backflow prevention is required, Hydro- Rain’s HRA Anti-Siphon Valve is a “must have". Its advanced design incorporates a glass filled polypropolene lid able to withstand more heat that competitors PVC lid. HRA valve meets ASSE, CSA and IAPMO standards.

Features and Benefits

• Automatic valve—For convenience and water savings when used with 24-volt irrigation controllers

• Rugged—Double seal TPR diaphragm ensures years of reliable performance
• Stainless steel metering system—Provides a continual cleaning action every time the valve goes on or off
• Commercial grade construction—Glass-filled nylon jar-lid and PVC body for long life and heavy-duty performance
• Leak proof—Buna-N valve seat seal provides positive closure preventing seepage
• Flow control—Meets the needs of your landscape and environmental conditions by “tuning in” sprinkler water droplet size
• Manual internal bleed—Allows manual watering with no external discharge
• HRC 900 Adaptabilty—Combines HRA 075/100 with HRC 900 isolation controller module and to run 1–4 valves in remote location
